I agree. Both of the equations come out to 2x^2+14x+20
(2x+10)(x+2)
Use the FOIL method
2x^2+4x+10x+20
Combine like terms
2x^2+14x+20
(2x+4)(x+5)
Use the FOIL method
2x^2+10x+4x+20
Combine like terms
2x^2+14x+20
Answer:
D. 85
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180. Since we already know 2 of the interior angles of that triangle (40 and 55), we can subtract those two angles from 180 to find x.
180 - 40 - 55 = 85
